Improvement in car-couplings

LEWIS SIBLEY, OF RAMAIO, NEW YORK.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 168,190, dated September 28, 1875; application filed August 21, 1875.

. To all whom it may concern:

Be it known that I, LEwIs SIBLEY, of Ramapo, in the county of Rockland and State of New York, have invented a new and. Improved I Gar-Coupling, of which the following is a specition, and allows the coupling with cars hav-" ing platforms of different heights. The draw-.

head may be made with open top and bottom, or closed, as described, a slotted recess being in the latter case provided for the weighted lever of the coupling-link. The link 0 is swiveled to a pivot-block, l), at the rear part of the draw-head, so as to turn freely therein. The front end of the link extends to the outside of the mouth of the draw-head, and has an arrow or spear shaped head, 0,

With a hole for the common pin-and-link coupling. The -arrowhead 0 is rounded off in front, and beveled at the sides, for the purpose of facilitating, by the contact with curved mouth of the draw-head, the ready swiveling or'revolving of the link into vertical direction. The horizontal position of link for coupling is produced by a supporting band-sprin g, E, that is attached to the rear end of the drawhead, and extended forward under the link, sustaining it for coupling, While giving way sufficiently when being coupled with lower draw-head.

tending to the side of the draw-head, and being connected by a chain or rope with the uncoupling mechanism at the platform or top of a the car.

When the Weighted lever is raised the link turns, and the arrow-head assumes a vertical position, in which the uncoupling is readily produced. When the lever is dropped the arrow-head of the link is in horizontal position, and is turned, by the contact with the approaching draw-head, readily into vertical position, so as to pass through the mouth of the same, assuming instantly its horizontal position, and coupling thereby the drawheads.

The ready turning and swinging of the. pin by means of the pivot-block renders the coupling action perfectly reliable, the same effect .being, however, also produced bysubstituting in place of the weight of the lever a spiral spring around the link, which spring carriesv the link into horizontal position as soon as its head orlever is released.

The car-coupling is very simple in construction, adapted to connect cars with platforms of diiferent heights, and to readily couple and. uncouple without the least danger.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of swiveled link G, pivoted block D, supporting-spring E, and weighted lever F, as and. for the purpose specified.
